本文报告已作癫痫灶切除术的27例癫痫患者术前脑电图检查结果,以探讨其定位诊断规律。患者年龄14～53岁,平均病程11.04年。病因及发作型式多种。癫痫灶位于颞叶者16例,余分别在额、中央及枕区。作者强调不管临床发作型式如何,蝶骨电极需常规应用。作者用自己设计的密集电极方法探测小癫痫灶,效果满意。癫痫定位诊断着重点应放在痫波阵发间歇期。本文提出典型颞叶癫痫脑电图的三点诊断依据。对双侧颞叶孤立发放痫波问题也作了讨论。本组患者术前脑电图所确定的癫痫灶全部经皮层电图证实。
This article reports 27 cases of epileptic fistula resection for epilepsy patients preoperative electroencephalography results to explore its positioning diagnosis. Patients aged 14 to 53 years, the average duration of 11.04 years. Etiology and type of attack a variety. Epileptic foci located in the temporal lobe in 16 cases, respectively, in the amount of the central and occipital. The authors emphasize that the sphenoid electrode needs to be routinely applied irrespective of the type of clinical attack. The author uses his own design of dense electrode detection of small epileptic foci, with satisfactory results. Epilepsy positioning diagnosis should focus on intermittent episodes of epileptic waves. This paper presents three typical diagnostic criteria of temporal lobe epilepsy EEG. The issue of releasing epileptic waves in bilateral temporal lobes was also discussed. The group of patients identified by preoperative electroencephalography epileptic foci all confirmed by transcutaneous electrodialogram.
